A man living just outside Detroit was given a ticket for having his car idling in his driveway. In the harsh northern winters, many drivers idle their cars so they can jump into the warmth for their commute instead of having to shiver and shake until the car warms up on the drive. However, citing concerns of thieves jumping into the running cars and speeding away and fuel waste, as well as environmental threats, the authorities do ticket drivers for idling their cars.
